A shocking video clip of model Choi Hye Yeon in a changing room was leaked online on Saturday (Dec 7).

According to a K-pop insider report, the video was accompanied with a Korean title which reads: "Maxim Model Choi Hye Yeon Changing Room Hidden Cam Leaked version xxxx Exposure".

The video appears to be recorded from a camera concealed inside some sort of bag, and Choi Hye Yeon doesn't seem to be aware of existence of the person recording the video.

Apparently, the camera was spotted by a female staff at the end of the clip who yelled, "What are you doing here?"

However, there is also speculation that the video was created by her game developer sponsor, AoA (Arrogance of Aggresssion) for which Choi is the main promotion model as she was seen wearing the cosplay outfit of one of the game character.

What do you think? Is this a attempt at making a brand name viral, or a honest case of outrage of modesty?
